Abstract: A positioning method adapted for a signal transmitting device and a server is provided. The positioning method includes: transmitting a reference signal by using the signal transmitting device having a low power mode and a high power mode; receiving the reference signal and determining a position of the signal transmitting device according to the reference signal and a signal strength and distance curve diagram by the server; and configuring the signal transmitting device to switch to one of the low power mode or the high power mode by the server.

Abstract: An auxiliary mounting device includes a mounting seat mounted with an electronic device thereon and having an upright rear wall formed with a through hole that is aligned with a rear opening unit in a housing of the electronic device. An upright reflecting plate is connected to a rear surface of the rear wall, is disposed adjacent to the through hole, is pivotable about a vertical axis relative to the rear wall, and is operated at a used position, where a desired angle is formed between the reflecting plate and the rear surface of the rear wall such that sound waves of an audio output reproduced by a loudspeaker of the electronic device propagate rearwardly from the electronic device through the through hole in the mounting seat and are then reflected by the reflecting plate so as to propagate sidewardly and frontwardly.

Abstract: A global position system device including a host and a plurality of direction indicating lights is provided. The direction indicating lights are disposed at the host, wherein each direction indicating light is represented as one direction. The host controls the direction indicating lights such that one of the direction indicating lights is bright and the others are dark. Then, users are indicated by the direction indicating lights to make a turn or keep running straightforward.
